This technology is called the 5 sense Virtual Reality technology. The perfect digital timeline of Earth is a digital gnosis database of all living beings that ever lived on earth, including humans, animals, insects, Bacteria and single atoms, from birth to death/current state. The entire family tree of organisms is documented meticulously-- Every human being that ever existed on Earth has their life stored in the timeline frame-by-frame and atom-by-atom. This also means that the computer was able to use AI to record the 5 senses and thoughts of a person from birth to death/current state. This permits the AI to generate a realistic simulation of any person that ever lived on Earth for users’ to experience from a first person point-of-view and through their 5 senses.
